Having anxiety

I'm 6 days post unprotected sex and 5 days dpo. When I had sex it was the day before my ovulation day. And I feel like I am or I'm gaslight myself that I'm pregnant idk. I took a test today and it was negative, probably too early to test. I've had unprotected before but I never felt like this afterwards, this is new thing for me.

I'm on Nexplanon and I felt like it has shifted a little bit deeper into my skin and can't feel it as much as I used too.
